Abstract

Particles harder than the seal material are mixed with the latter. As a result, small, uniformly distributed elevations on the seal surface are produced by such particles located close to the seal surface.

Description

Die Erfindung bezieht sich auf eine gummielastische Dichtung nach dem Oberbegriff des Patentanspruches 1.The invention relates to a rubber-elastic seal according to the preamble of claim 1.

Treten zwischen Gummidichtungen und benachbarten Karosseriebereichen, insbe­ sondere lackierten Karosserieblechen, Relativbewegungen auf, so können Knarzge­ räusche entstehen. Sie entstehen dadurch, daß die Dichtfläche der Dichtung an der glatten Gegenfläche unter Umständen über einen größeren Flächenbereich "kleben bleibt" und erst nach einer zunehmenden Relativbewegung zwischen Dichtung und Gegenfläche schlagartig freikommt. Dabei entstehen unerwünschte Geräusche, die erheblich stören können.Occur between rubber seals and neighboring body areas, esp special painted body panels, relative movements, so creaking there are noises. They arise from the fact that the sealing surface of the seal on the stick the smooth counter surface over a larger area " remains "and only after an increasing relative movement between the seal and The counter surface suddenly comes free. This creates undesirable noises can significantly disrupt.

Eine Dichtung der eingangs genannten Art (DE 33 35 150 C1) ist auf der mit der Gegen-Dichtfläche in Kontakt kommenden Oberfläche mit einer zusätzlichen Be­ schichtung versehen, in die Glas- oder Kunststoffkügelchen eingelagert sind. Die zusätzliche Beschichtung kann ein Lack sein. Das Aufbringen eines derartigen Ku­ gelgleitlackes bedeutet einen erheblichen Kostenaufwand.A seal of the type mentioned (DE 33 35 150 C1) is on the with Counter sealing surface coming into contact with an additional loading Layering in which glass or plastic beads are embedded. The additional coating can be a varnish. The application of such a Ku gel slip varnish means a considerable expense.

Der Erfindung liegt die Aufgabe zugrunde, eine gummielastische Dichtung der im Oberbegriff des Patentanspruchs 1 genannten Art zu schaffen, die eine einfacher und daher auch kostengünstiger herstellbar ist und die beschriebenen Knarzgeräu­ sche ebenfalls vermeidet.The invention has for its object a rubber-elastic seal in The preamble of claim 1 to create a type that is easier and is therefore also cheaper to produce and the described creaking also avoided.

Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Maßnahmen gelöst.This object is achieved by the one specified in claim 1 Measures solved.

Weitere vorteilhafte Einzelheiten der Erfindung sind Gegenstand der Unteransprü­ che.Further advantageous details of the invention are the subject of the dependent claims che.

Das Beimischen der Partikel in das zur Herstellung der Dichtung verwendete Mate­ rial ist einfach zu bewerkstelligen, ebenso das Verarbeiten eines derartig veränder­ ten Materials in den üblichen Fertigungsprozessen eines Dichtungsprofils. Beim Abkühlen des verwendeten Materials, das Gummi oder auch jedes andere gum­ mielastische Material sein kann, kommt es zu einem geringfügigen Schrumpfen des Grundmaterials. Die Partikel unterliegen diesem Schrumpfen in einem weit geringe­ ren Ausmaß, so daß die nahe an der Oberfläche des Dichtungsprofils liegenden Partikel die geringfügig über die Rest-Oberfläche hervorstehenden Erhebungen bil­ den. Die Erhebungen führen dazu, daß die Dichtung nur mehr in sehr geringen Flä­ chenbereichen an der Gegenfläche anliegt, so daß der die erwähnten Knarzgeräu­ sche auslösende Stick-Slip-Effekt nicht mehr auftritt. Die Dichtung "saugt" sich ge­ wissermaßen nicht mehr an der Gegenfläche fest, sondern beginnt schon bei relativ geringen Relativbewegungen zwischen Dichtung und Gegenfläche zu gleiten. Trotz­ dem ist noch eine zufriedenstellende Dichtwirkung erreichbar.Mixing the particles into the mate used to make the seal rial is easy to do, as is processing such a change th material in the usual manufacturing processes of a sealing profile. At the Cool the material used, the rubber or any other gum may be mielastic material, there is a slight shrinkage of the Basic material. The particles are subject to this shrinkage to a very small extent ren extent so that the lie close to the surface of the sealing profile Particles with bumps protruding slightly beyond the rest of the surface the. The surveys mean that the seal is only in very small areas Chen areas rests on the counter surface, so that the creaking mentioned ceasing stick-slip effect no longer occurs. The seal "sucks" itself in a sense no longer stuck to the counter surface, but begins with relative small relative movements between the seal and the counter surface. Despite a satisfactory sealing effect can still be achieved.

Es kann sich als zweckmäßig erweisen, die Partikel nur in bestimmten Teil-Quer­ schnittsbereichen eines Dichtprofils beizumischen, was im Koextrusionsverfahren ohne weiteres realisierbar ist.It may prove useful to cross the particles only in certain parts Mixing sections of a sealing profile, what in the coextrusion process is easily realizable.

Die Erhebungen sollen eine Höhe haben, die bei bestimmungsgemäßem Anpreß­ druck der Dichtung ein Anliegen der zwischen den Erhebungen liegenden Oberflä­ chenbereiche auf der Gegenfläche verhindert. Dadurch kommt es nicht zu dem schon kurz angedeuteten "Festsaugen" mit dem plötzlichen Lösen der Dichtung von der Gegenfläche.The elevations should have a height that is the intended pressure pressure of the seal a concern of the surface lying between the elevations  areas on the counter surface prevented. This does not result in that already briefly hinted at with the sudden loosening of the seal from the counter surface.

Zweckmäßig sind die beigemischten Partikel kugelförmig und haben einen niedrigen Reibungskoeffizienten. Sie können aus Glas, Polyamid aber auch aus PTFE beste­ hen.The particles mixed in are expediently spherical and have a low content Coefficient of friction. They can be made of glass, polyamide but also best of PTFE hen.
